mysql不能启动，但是navicat for mysql 和phpMyadmin可以连接

出现：

UPUPW_ANK_MySQL: Table 'mysql.plugin' doesn't exist
2021-02-12T03:00:45.666150Z 0 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
2021-02-12T03:00:45.671350Z 0 [ERROR] Can't start server: Bind on TCP/IP port: No such file or directory

2021-02-12T03:00:45.673458Z 0 [ERROR] Aborting
使用mysql_upgrade无法解决，不知道是哪的问题

数据库端口3306被另一个数据库软件占用了，排查下是不是环境混用导致启动的另一个环境的数据库。
